SWING-SPOUT COMPRESSION-FAUCET.

Application filed August 21, 1914, Serial No. 857,941.

To all whom it may concern:

Be it known that I, JAMEs T. POWER, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Swing-Spout Compression-Faucets, of which the following is a specification.

My invention relates to improvements in faucets and applies more particularly to the type of faucets known as swing-spout compression basin cocks, wherein the spout comprises the handle by which the water may be turned on or shut ofi.

-Theobject of my invention is to provide such a device wherein a simple arrangement will make it possible to prevent the leaking of water at the joints, and wherein the valve will close in line with the water pressure.

l/Vith the above and other objects in view, my invention comprises the new and useful details of construction, arrangement and combination of parts, which will be hereinafter fully described, illustrated in the annexed drawings, and pointed out specifically in the appended claims.

In the accompanying drawings, to which reference will be had, the preferred embodiment of my invention is illustrated, like reference characters referring to like or corresponding parts throughout the several views.

Figure 1 is a front elevation of the basin cock of my invention. Fig. 2 is a fragmentary detail sectional view of the spout member. Fig. 3 is a vertical sectional view of my assembled basin cock. Fig. 1 is a detail view of the central core. Fig. 5 is an adaptation of the main body, showing the arrangement for use on a horizontal pipe. F 6 is'a sectional View through the faucet taken on line 2-2 Fig. 3.

Referring to the drawings, numeral 1 designates the main body of my basin cock, adapted to be mounted to a basin or sink in the usual well known manner, the upper provided with external screw threads 2.

Numeral 3 designates the central core which is adapted to fit into the upper end of main body 1, a seat therefor being provided at 1 on the inner wall of the main body, whereupon tapered face 4 on the core isadapted to engage. Core 3 is recessed upward centrally from thebottom and a valve seat 5 is provided on the lower end.

Specification of Letters Patent Patented June 11, 1918.

Renewed November 10, 1917. Serial No. 201,400.

An external collar 6 is provided adjacent the lower end of the core, and a packing nut 7 is adapted to engage the collar and to be screwed in place on threads 2, packing being introduced between collar 6 and the upper end of main body. Lugs 8 on the outer wall of core 3, below collar 6, provide means for locking core 3 from rotation in the main body, corresponding internal notches being provided on the upper portion of the main body to register therewith. Core 3 is equipped with external tapered ground joint faces 9 and 10, and about these faces, a spout member 11 provided with a hollow spherical base is adapted to fit, similarly tapered faces 9 and 10 being provided in the interior of the spherical base portion of that member. Nut 12, having a screw thread stud fixed thereto is carriedon the upper end of core 3, and a coil spring washer 13 is interposed between the base of the nut and the upper face of the spout member.

Within the central recess of core 3, I provide a vertically slidable valve stem 14, the upper end thereof fitting into a socket in the upper interior portion of the core. Valve stem 14: is provided adjacent the upper end thereof with a cross pin 22 loosely fitted into a hole through the stem. The lower end of stem 14: is provided with wings 16 which are substantially radial of the stem and which fit against the walls of the opening in the lower end of the core. A stud 17 is screwed into the lower end of the stem 14, and a packing gasket 19 is held in place therein by a threaded valve washer 18. A look nut 20 is provided below the washer 18, to lock the same securely in. place.

Above ground joint face 10 on core 3,

the walls of that element are restricted, and

in this restricted portion I provide two cam slots 21 on the opposite sides ofthe core. Slots 21 extend diagonally upward and in opposite directions, and a horizontal pin 22 carried in valve stem 14 is adapted to protrude tlierethrough. On opposite sides of the inner walls of the spherical base of spout member 11 are positioned pairs of parallel spaced apart projecting ribs 23, each pair of ribs being adapted to received therebetween the protruding end of cross pin 22 of the valve stem. Ribs 23 are tapered on their inner edges to substantially form a continuation of the ground joints 9 and 10',

joints. In order to prevent endwise movement of cross pin 22 in the valve stem, I have filled in the space between the ribs of each of the oppositely positioned pairs, for a portion of the depth of those ribs.

In assemblying my faucet, the base is attached to the basin or sink in the usual manner. The valve stem 1%, with the gasket and valve washer secured in place, is inserted into the central recess in core 3, and pin 22 is inserted in place in the opening therefor in the valve stem, by being entered through one of the cam slots 21. The core is then inserted into the main body and packing nut 7 screwed in place on threads 2. The spout member 11 is then placed about the core, the protruding ends of pin 22 being entered between ribs of the spaced pairs of ribs in the interior of the spout base. Coil spring 13 is placed about the upper portion of the core and nut 12 screwed down, forcing the ground joints on the core and spout into contact.

In operation it will be readily seen that by swinging the outer end of the spout forward, the ends of pin 22 will be likewise swung with the spout, by reason of the engagement of pin 22 with cam slots 21 in stationary core 3. This movement of stem 14 will unseat the valve gasket 19 from seat 5, and allow the water to enter core 3 between wings 16 of the valve stem. The water will pass through slots 21 and out spout 11. Likewise, the reverse movement of spout 11 will cause pin 22 to draw stem 1 f upward, by the engagement of that pin with the cam slots 21, and the gasket 19 will be drawn against seat 5. By reason of the provision of a loose fit between cross pin 22 and valve stem 14, the friction between cross pin and slots 21 is greatly reduced.

From the foregoing description it will be seen that I have provided a faucet wherein the danger of leakage has been reduced to a minimum and wherein the valve closes in line with the pressure of the water.

While I have herein described and illustrated the preferred embodiment of my invention, I do not wish to be limited strictly to the construction shown, as it is obvious that the details of arrangement and construction may be varied slightly without departing from the spirit of my invention.

Having thus described my invention, what I claim is 1.
